Here's an airplane (an Airbus 320):
It's about 37m long. It can seat about 200 passengers.
Here's a bigger airplane (the A380):
It's twice as long (about 73m). It can seat four times as many people (850 passengers). It clearly is a bigger plane: it has two levels, windows for each level, and note the windows are the same size as on the A320. The hatches are all the same size, because they're built for the same thing (people). The cockpit windows are the same size. The cargo doors are the same size.
No one at Airbus decided to simply take the A320 design and scale it entirely up by a factor of 2, because that way, it would be a bigger, grander plane. The doors aren't twice as big on the A380. The windows aren't twice as big. There are design consequences to upscaling.
And before anyone tries: even bigger planes that have only one level (e.g. Boeing 767, etc....) have MORE WINDOWS that are the same size as the smaller one, hatches that are the same size, etc....
The "hatches" aren't only not the same size as they were on the TMP Enterprise (as I already showed you and you're predictably ignoring), but they clearly don't even have the same function!
We see an airlock in the opening Nibiru scene of Into Darkness
. When opened was the same height as the nearby engineering hull windows.
I've already posted overwhelming evidence that the windows (which are not
simply scaled up versions of the originals in size, shape or placement despite your claim. They look vaguely similar but that's it) are far larger than they were. I think it's time to drop that comparison.
Here is it again, just for kicks:
Any exterior shot of the new Enterprise makes it clear the saucer rim and neck windows are all of that height and many of that width.
